A few common gear tooth shapes.
Gears should always touch each other on at least one point on what is called the line of action, and the teeth are shaped in a way that maintains a constant ratio between the rotation speeds of both gears. The notebook shows 3 ways of generating gear tooth shapes which solve this problem.
The infinite rotation input is defined in my inputs notebook:
Thats so cool. I have been trying to make a gear generator for a while, without success. I ended up finding a decent calculator on the web that produced good working involute gears, but it was about the 3rd I tried. I like the modular calculation system
Thanks. I suspect this one doesn’t quite make working gears, it doesn’t do the more subtle real world things like rounding edges, etc.
